abstract

Sandia National Laboratories has developed a new explicit nonlinear transient dynamic finite element code called Presto and an associated implicit code called Adagio. This paper describes a process used to assess the ability and efficiency for sharing the computational workload of a multiple impact crash simulation between the explicit (Presto) and the implicit (Adagio) codes to minimize computation time. A numeric example of this hybrid simulation process is given that applies to a dynamic beam impact scenario. Results from simulations using each code will be compared with the hybrid simulation and discussed.
